DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1645Z April 21, 2010

Northern Gulf of Mexico:
A hot spot and smoke plume can be seen in satellite imagery from the oil
rig explosion and fire in the northern Gulf of Mexico off the southeastern
Louisiana coast. The thin to locally moderately dense smoke plume is
fanning out as it moves in a southeasterly direction.

South Central Canada/Northern and Central Plains/Great Lakes Region/Ohio
Valley:
GOES visible imagery this morning shows an area of aerosol stretching from
Saskatchewan Province in south central Canada southeastward across the
Dakotas to southern Minnesota and Iowa. The aerosol also extended farther
to the east and southeast to at least as far as the Ohio Valley. It
is believed that leftover smoke from the large number of daily fires
burning across south central Canada, the Dakotas, and western Minnesota
are responsible for at least a portion of this aerosol. The National
Weather Service Air Quality Forecast Guidance product also indicates smoke
across much of this region... http://www.nws.noaa.gov/aq/sectors/conus.php

THE FORMAT OF THIS TEXT PRODUCT IS BEING MODIFIED. IT WILL NO LONGER
DESCRIBE THE VARIOUS PLUMES THAT ARE ASSOCIATED WITH ACTIVE FIRES. THESE
PLUMES ARE DEPICTED IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

JPEG:   http://www.osdpd.noaa.gov/ml/land/hms.html
GIS:    http://www.firedetect.noaa.gov/viewer.htm
KML:    http://www.ssd.noaa.gov/PS/FIRE/kml.html

THIS TEXT PRODUCT WILL CONTINUE TO DESCRIBE SIGNIFICANT AREAS OF SMOKE
WHICH HAVE BECOME DETACHED FROM AND DRIFTED SOME DISTANCE AWAY FROM THE
SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. IT WILL ALSO
STILL INCLUDE DESCRIPTIONS OF BLOWING DUST.

ANY QUESTIONS OR COMMENTS REGARDING THESE CHANGES OR THE SMOKE TEXT
PRODUCT IN GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov


 


Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
